Hello.Will these schematic work to control 2 separate meters of led strips? (Led strip Rgb Ip65 7.2w/m).Tell me if im wrong and why, in what im going to type.

-Resistance between the Arduino and the gate will limit the current, its not really needed since its a mosfet and the current will be low, but wont hurt right (220 ohm?).

- I have to look for a logic level mosfet, that is full on with 5V, and that can handle the current it will be asked for. (Each led takes about 20ma full white, so 20ma * 30leds = 600ma for each colour, so i get one that can handle 1,5A).

- If i want to get 4 strips, i simply use a shift register 74hc595 to get more PWM outputs.

No. PWM doesn't work through a shift register. (At least not easily...)

Why? Ive seen some tuturials using shiftpwm arduino library. "ShiftPWM is a library for Arduino to control many PWM outputs using shift registers (for example 74HC595). "

And about the FET, will this one http://www.mixtronica.com/electronica-componentes-electronicos-semicondutores-transistores/3759-ap2306agn-hf-3tr-mosfet-n-30v-0-035-ohm-sot23-ap2306agn.html, do the same as A0I514?
